METAL wrnnow oorisrnuorronl Original application filed February 1, 1926, Serial No. 85,095. Divided and. this application filed November 26,1826} Seria1 No.'150:,78 5.l

The principal object of the invention is to provide an improved guide of the char- "acter described which is inexpensive to manufacture, is easy to, install, does not necessitate any counter-sinking of the'heads of the attaching screws, 2. weatherproof closure with both the stiles of thesashesi and the meeting rails thereof.

Other objects and additions of the invention will be apparent to those skilled in the artupon a full understanding of the nature of theimproved guide. In order thatthe invention may be readily understood, one preferred structural formof the same is herein illustratedand described, but it will of course be appreciated that the inventon is susceptible of embodiment in other slightly modified" forms coming equally within the comprehensive scope of the claims.

In the accompanying drawing:

Fig. l is a front elevation of a window equipped with the sash guides of the invention;

Fig. 2 is a vertical section through the window, taken on the line 22' of Fig. 1;

Fig. 3 is a horizontal section through the window, taken on the line 3-3 of Fig. 1;

Fig. 4; is a horizontal section through one of the sash guides, taken on the line H of Fig. 2; and

Fig. 5 is a vertical section through the sill near one of the jambs, the lower sash being raised in order to show the arrangement and notching of one of the sash guides with respect to the sill.

The window construction illustrated in the drawing consists of a frame 10, a lower sash 11 and an upper sash 12. The sashes 11 and 12 areslidably mounted in two oppositely disposed sash-guiding strips 13 which are attached by screws 14 to the jambs 15 and 16 of the frame. The present invention resides in the construction of the strips 13. The other novel structural features shown are covered in my copending application Serial No. 85,095, filed Feb. 1, 1926, of which this application is a division.

The strips 13 extend the full height of the jambs and occupy thespace on the jambs between the inside plane of the upper sash This invention pertains to metallicwinguide for slidingf which face toward the jambs, and relatively and presents the outsideplane of the lower sash. The

strips -13"are of a triple channel format-ion, havingrelatively' wide middle-channels 17' narrow side channels 18 which facetoward the sashes. The side walls ofthe channels 18 are resilient and bear with spring pres sure against the marginal portions 19 of the stiles ofthe sashes, the outside edgesof the stiles of the lower sash. 11 being guided in the inside channels of the strips, and the inside'edgesof the stilesof the uppersasli eing side walls ofthe channels 18 are not parallel 7e 1 angles relative thereto and converge in the guided in'the outside channels; The

with the planes of the sash, but are set at direction of the openings in such channels,

f -Eh! T OFFIC L I thereby atl'ording tight and relatively fric tionless line contact with the marginal por-' tions ofthe sashes. 5 s

The middlechannels 17 in the strips constitute ribs 20 -.w'hich space and extend between the upper and lower sa'sl1es;""The ribs 2 20 are made concave in order to accommodate the heads of the attaching screws 14, which heads will not-project beyond the front face of the ribs and need not be counter-sunk in the same.

At those mid-way points on the guides where the top rail 21 of the lower sash is positioned alongside the bottom rail 22 of the upper sash when the window is closed, the recessing of the front faces of the ribs 20 is discontinued, forming flat areas 23 on the ribs, which areas fit closely against the ends 24: of those portions of the meeting rails which extend toward each other in hook relation between the sashes and produce at such points effective closures between the corners of the sashes, and the guide strips. The upward movement of the lower sash 11 is limited by two stop blocks 25 which are positioned in the upper ends of the inside Channels 18 in the guide strips, the marginal portions 19 of the stiles of that sash being adapted to abut against such blocks when the sash reaches its fully raised position.

The sill 26 of the frame is preferably provided with a substantially vertical wall por tion 27 and the lower outside marginal portion 28 of the bottom rail of the lower sash, which is in the same plane as the marginal portions 19 of that sash, is wedged closely Hil against the wall portion 27 when the sash to the sill at a point intermediate the guide strips.

I claim: j

.1. In a metallic windowconstruction, the combination with a frame and two independently movable sashes, of a sash guide comprising a sheet metal strip formed with a longitudinally extending middle rib and two channels along the opposite sides of the i rib for the reception of marginal portions ofpthe sashes, said rib being formed with a shallow channel in the face thereof to afford clearance for the heads of attaching screws.

,2. In a metallic window construction, the

V combination with a frame and two independently movable sashes, of a sash guide comprising a sheet metal strip formed with a longitudinally extending middle rib and two channels along the opposite sides of the rib for the reception of marginal portions of the sashes, said rib being formed with 3.

shallow channel in the face thereof to afford clearance for the heads of attaching screws, and said channel in the face of the rib being interrupted at one point to present a substantially flat face against which the ends of the meeting rails of the sashles may fit closely when both of the sashes are in closed positions.

3. In a metallic window construction, the combination with a frame and two independently movable sashes, of a sash guide j comprising a sheet metal strip formedwith two longitudinally extending channels for the reception of marginal portions of the sashes, one of said channels having a block positioned in and closing the upper end of the same to provide limiting abutment for the marginal sash portion slidable therein.

4. In a metallic window construction, in combination with a frame and two independently movable sashes, of a sash guide provided with a longitudinally extending channel for the reception of-a marginal portion of one of the sashes, said strip being positioned against the jamb of the frame and notched out to fit about a substantially vertical portion of the sill whereby to wedge the sash tightly against the vertical portion of the sill when the sash is in closed position.

In testimony whereof I have hereunto signed my name.

THOMAS P. SHEAN.
